docs: add solid list search usage example

[zobweyt]

This pull request adds a usage example for the solid-list utility, demonstrating how to create a search results list.

Initially, I found it unclear how to create a single list, as the existing interactive examples only showcased the createMultiList functionality. To address this, I added an example for createList.
